Hi, gtk+-2.14.6 compilation was failed for arm-linux with directfb. I had compiled gtk+-2.14.6 with configure option --with-gdktarget=directfb --without-x --disable-gdiplus --without-libtiff --disable-gtk-doc --disable-man --disable-glibtest --without-libjasper. It is to be noted that glib version is glib-2.18.3, directfb version is 1.2.0.
Then, I applied the patch available in the link: http://bugzilla.gnome.org/attachment.cgi?id=122159&action=view The compilation broke even after that, so the following change as per the patch was reverted back in the file: gtk+-2.14.6/gdk/directfb/gdkwindow-directfb.c directfb/gdkwindow-directfb.c @@ -99,7 +114,6 @@ while (tmp_list) { GdkWindowObject *private = GDK_WINDOW_OBJECT( tmp_list->data ); - GdkWindowImplDirectFB *wimpl = GDK_WINDOW_IMPL_DIRECTFB( private->impl ); if (private->update_freeze_count) { Ultimately, compiled well. But, when I run gtk-demo provided with the package, in the target device the application crashes, showing Segmentation fault. Here is the back trace...........

Can anyone help me to work with gtk with directfb backend.........? Regards Dhananjoy
